How to use a green texture map from a game character?
Well, I had the same question for the same reason and I finally worked it out. Apparently it's a Unity thing. What you're looking at is an RGBA texture map. G has ambient occlusion, R has metallic, B has something they call a &quot;Detail Mask&quot; but I didn't immediately get the purpose, and A has has the &quot;smoothness&quot; mask which is an inverse of roughness in the form of 1-sqrt(roughness). Here is more than you probably want to know: https://raytracing-docs.nvidia.com/mdl/api/html/mi_neuray_example_distilling_unity.html
